The UMH-KJMR-1 36 rpm 5-Roller Mixer is a compact laboratory
tube mixer designed to combine rolling and swinging motion
for continuous and uniform sample agitation.
With 5 rollers, a fixed speed of 36 rpm,
a swing angle of ±11° and a maximum loading capacity of
0.8 kg, it is suitable for blood samples, viscous liquids
and liquid-solid suspensions used in clinical, diagnostic and research laboratories.

Typical Applications
The UMH-KJMR-1 is suitable for continuous mixing of laboratory samples where
gentle rolling and repeated inversion are preferred over high-speed vortex mixing.
Typical applications include:
- Blood sample mixing
- Anticoagulated blood tube mixing
- Viscous liquid mixing
- Liquid-solid suspension mixing
- Clinical laboratory sample preparation
- Diagnostic laboratory workflows
- Biomedical and life science research
Combined Rolling and Swinging Motion
Unlike a standard roller that only rotates the sample tubes, the UMH-KJMR-1
combines rolling movement with a ±11° swinging action.
The combined motion continuously changes the position of the liquid inside
the tube, helping promote more uniform sample mixing during extended operation.
This mixing principle is particularly suitable for samples that benefit from
gentle continuous agitation rather than aggressive high-speed shaking.
36 rpm Continuous Mixing
The mixer operates at a fixed rated speed of 36 rpm.
The continuous operating mode is designed for routine laboratory procedures
that require stable rolling over a defined period.
Mixing duration should be determined according to the sample type, tube size,
fill volume and laboratory procedure.
5-Roller Platform
The UMH-KJMR-1 is equipped with 5 parallel rollers.
The roller spacing is designed to accommodate different compatible laboratory
sample tubes while maintaining stable rotation during operation.
The usable roller length is approximately 230 mm, providing
space for multiple tubes depending on their external diameter and length.
Suitable for Blood Sample Mixing
The rolling and swinging action makes the UMH-KJMR-1 suitable for routine
blood sample mixing, including compatible anticoagulated blood collection tubes.
The low-speed continuous movement helps keep samples in motion without the
intense agitation associated with high-speed vortex mixers.
For clinical sample handling, tube type, mixing time and laboratory procedures
should follow the requirements of the relevant collection tube manufacturer
and the laboratory’s validated protocol.
Compact Design for Laboratory Workspaces
With overall dimensions of approximately 260 × 155 × 140 mm,
the mixer occupies relatively little bench space.
Its compact structure also allows operation inside compatible temperature-controlled
equipment such as incubators or refrigerated cabinets, provided the operating
environment remains within the specified temperature and humidity limits.

Roller Mixer vs. Vortex Mixer
The UMH-KJMR-1 is intended for gentle continuous tube mixing rather than
high-speed individual tube agitation.
- Roller Mixer: better suited to continuous rolling of multiple
compatible tubes, blood samples and suspensions. - Vortex Mixer: better suited to rapid, high-speed agitation
of individual tubes or small containers.
The appropriate mixer should be selected according to the sample type,
required mixing intensity and laboratory workflow.
